Description

Note : Les descriptions sont présentées dans la langue officielle dans laquelle elles ont été soumises.



The present invention relates to a device for
cleaning planar surfaces such as windows and, in particular,
relates to a combination device providing a sponge and a
squeegee attached to a frame that is connected to a handle.
Such combination sponge-squeegee devices are well-
known and have been proven ~o be most useful in washing windows
in such as cars, homes and the like. The sponge is designed
to carry liquid, such as a soapy water for cleaning windows
and generally presents a rough or abrasive surface to assist
in the cleaning process. A flexible elastomeric or similar
blade is formed along one edge of the device to provide a
squeegee for removing ~he dirty, soapy water from window.
The sponge and squeegee usually are disposed along opposite
margins of the device with a handle connected with and
axtending from the central portion of the device.
Several devices are known which have this or
simi~ar configurations. U.S~ Patent 4,107,812 to Lantto
discloses a structure in which there is a blade and sponge
attached to an elongated holder by way of T-shaped protrusions
and recesses. A rod-like handle extends from the holder.
U.S. Patent 3,873,747 to Seymore discloses a
washer/squeegee in which squeegee and sponge members are
attached to a holder by way of protrusions and recesses.
The handle forms a fluid reservoir. U.S. Patent 3,656,202
to Paton discloses a sponge/squeegee combination in which
the squeegee is sandwiched between the sponge and sponge
platform and projects therefrom su-f-ficiently for enabling
removal of the dirty water.
U.S. Patent 3,526,918 to Leland discloses a device
wherein the squeegee blade is attached to one side of the
sponge and a wire handle extends through central plane of the

3~

sponge. U.S. Patent 2,886,839 to Leopoldi discloses a
resilient water bottle having a squeegee blade and a sponge
disposed along opposite sides thereof. U.S. Patent 2,715,745
to Jacobsen discloses a sponge having a squeegee blade,
cemented to or-integrally molded therewith, along one edgeO
No handle is provided.
These prior devices generally require the assembly
of several different pieces and because of the geometry of
these pieces, the assembly normally is effected by hand.
A device of the above type which would lend itself
to automatic formation of the squeegee and sponge plat-Eorm
and yet would facilitate assembly of the sponge and handle
would be more desirable. Reduction of the number of components
for assembly also would result in great economy compared with
prior devices of this type. In addition, if the latter
advantages could be obtained while the product would be more
robust than prior devices,acceptance would be quickly for
the co~ing.
Accordîngly~ the invention provides a combination
squeegee/sponge cleaning device formed as a multiple durometer
single extrusion of s~nthetic reslnous material having a body
which generally defines three planes; one plane forming a
~lexible squeegee blade, a second plane havlng a sponge
carrying rigid platform and a sponge attached thereto; third plane Qf
rigid connecting portion with a handle secured thereto.
The preferred embodiment of this invention now will
be described, by way of example, with reference to the drawings
accompanying this specification in which:
Figure 1 is a perspective view of the device
providing a sponge, squeegee and handle constructed and
arranged in accordance with the invention;



--3--

3~

Figure 2 is a fragmentary sectional view of the
device taken generally along the lines 2-2 of Figure 1 and
in the direction illustrated by the arrows; and
Figure 3 is the bottom plan view of the device.
Briefly, a preferred embodiment of the invention
shall be described which presents both a sponge and squeegee
blade on a rod-like handle. In one position, the sponge may
be brought to bear against a planar surface to be cleaned
such as a car window. In another position, the device is
rotated about 180 enabling use of the squeegee to remove
dirty water from the pane of glass.
The combination squeegee/sponge cleaning device
constructed in accordance with the invention is i~dicated
generally in Figure 1 by the reference character 10 and
comprises an elongated body 12 providing a squeegee blade 14,
a central connecting portion 16 and a sponge platform 18 all
integral with one another and formed as an extrusion.
The body 12 generally defines three planes at
different angles, each of the elements comprisin~ the squeegee
blade, the central connecting portion and the sponge platform
generally defining a respective one of said planes. The
body 12 is formed as a leng-th of an extrusion of resinous
plastic material. The extrusion is cut into any desired
length. The character of the plastic forming the body 12
can be described as having a "dual-durometer" because of the
difference in rigidity or stiffness between two parts of the
same integral member.
Body 12 is formed as a unitary extrusion to provide
a durometer hardness for the squeegee blade 14 which is about
60 on a Shore A2 scale. Typically, squeegee blades have
a durometer hardness which is from about 50 to 70.

3~

The remainder of body 12 is formed of a ~aterial

having a much higher durometer number of 80 + 3 on a Shore D
scale. This durometer represents a relatively hard material
as compared to the squeegee blade and therefore, is more
rigid. Preferably, the body 12 is formed of polyvinyl chloride
having different durometers for the squeegee blade and for
the remainder of the body.
Squeegee blade 14 is a narrowr flat structure of
tapered cross-section, which is extruded as a unit with

co~nnecting portion 16 and presents a wiping edge 20.
Re~erring to Figure 2, it can be observed that sgueegee blade
14 is soft and is capable of being distorted to a position
indicated by the phantom lines at 14~.
Sponge platform 18 is a broad, flat elongated

structure also extruded as a unit with connecting portion 16.
A sponge element 22 is fastened to one side of platform 18 by
way of a cement or adhesive 24. Platform 18 terminates in a
lip or flange 26 which aids in registration of sponge 22 on
the platform la during the fastening operation.

Platform 18 forms an angle A with a plane normal to
the plane of central portion 16. Angle A is typically 15
degrees to provide the proper working angle for spDnge 22 on
a pane of glass while the device 10 is being held by the user.
Sponge 22 is formed of a foamed plastic material which is
~ available commercially "polyfoam". Sponge 22 provides the
moisture supply for the window w~sh; ng operation and can
include a soft abrasive applied to or integrally formed with

sponge 22 on a face 28 thereof.
The cleaning device 10 further includes a handle 30

fastened to frame 12 at connecting portion 16. Handle 30 is
normal to the longitudinal axis of body 12 ana comprises a
--5--

33~

simple wooden rod. Handle 30 is fastened to body 12 through
the intermediate of a bracket 32. Bracket 32 is fastened to
handle 10 by means of a rivet 34 (Figures 1 and 3) which
passes through the diameter of handle 30 and the thickness of
S bracket 32. Bracket 30 includes two flanges 38, (Figure 1 and
2) fastened to connecting portion 16 by fasteners such as
screws 40. Handle 30 preferably is made of wood and while
bracket 32 is made of metal which has been stamped to provide
the desired geometry to mate the handle 30 with the connecting
portion 16.
Thus, in use the combination squeegee/sponge cleaning
10 device is grasped by the handle 30 and used in one position
to apply soapy water to a pane of glass to wash the same.
Thereafter, the device is rotated around ~he axis defined by
~5 handle 30 about 1/2 turn to bring the wiping edge 20 of
squeegee blade 14 against the pane to remove the dirty water
from the surface thereof.
The cross-section of body 12 lends itself to the
extrusion of long members which are cut to provice the
individual lengths of body 12.
For example, the sponge carrying platform lB can
have a width of about 1 3/8 inch; connecting member 16 having
a width of about 9/16 th. inch, and squee~ee blade 14 having
a width of about 1/2 inch, with body 12 having a section of
about 3/32 inch in thickness,
The precise angles described hereln for the squeegee
blade and sponge carrying platform can be modified as desired
to facilitate the cleaning operation. The material of the
body 12 can be changed as desired. Likewise the material
from which handle 30 :is formed can be other than that described,
The durometer of the material forming the frame 12 likewise
can be varied so long as there is a difference in the durometer
selected for the support and for the squeegee,
